Silicone Bottle Cap

ABSTRACT

Embodiments of the invention relate generally to a silicone bottle cap comprising a silicone cap whose lower end is open and expanded. Inside the cap there are more than two circular sealing ribs, which are screwed with the threads on the outside of the mouth of the bottle to be sealed. The whole cap is made of silicone, which is a material of flexibility and elasticity. The bottle cap is placed above the bottle mouth and pressed downward to seal the bottle. The circular sealing ribs inside the cap can be screwed with the thread on the outside of the bottle cap. Therefore, the bottle cap will not easily fall off, and the sealing effect is improved. To remove the bottle cap, the lower end of the cap is flapped and the cap is pulled upwards. The bottle cap is easy to use.

DESCRIPTION OF RELATED ART

The background description provided herein is for the purpose ofgenerally presenting the context of the disclosure of the invention.Work of the presently named inventors, to the extent the work isdescribed in this background section, as well as aspects of thedescription that may not otherwise qualify as prior art at the time offiling, are neither expressly nor impliedly admitted as prior artagainst this present disclosure of the invention.

Bottle is one of the most common containers in daily life. Bottle isgenerally made of glass or plastic. To facilitate the pouring in and outof liquid, the cap should be fitted with the mouth of the bottle. FIG. 1and FIG. 2 show traditional connections between bottle and cap. Cap 01is composed of cap 011 and sealing plate 012, both of which are made ofmetal. The sealing plate 012 covers the mouth of bottle 100; the cap 011is screwed with the thread on the outside of the mouth of the bottle.The sealing plate 012 is tightened inside the cap 011. It is apparentthat the traditional bottle cap is not easy to use and the sealingeffect is poor. Some improvements are necessary.

DETAILED DESCRIPTION

In the following detailed description, for purposes of explanation,numerous specific details are set forth to provide a thoroughunderstanding of the various embodiments of the present invention. Thoseof ordinary skill in the art will realize that these various embodimentsof the present invention are illustrative only and are not intended tobe limiting in any way. Other embodiments of the present invention willreadily suggest themselves to such skilled persons having the benefit ofthis disclosure.

In addition, for clarity purposes, not all of the routine features ofthe embodiments described herein are shown or described. One of ordinaryskill in the art would readily appreciate that in the development of anysuch actual implementation, numerous implementation-specific decisionsmay be required to achieve specific design objectives. These designobjectives will vary from one implementation to another and from onedeveloper to another. Moreover, it will be appreciated that such adevelopment effort might be complex and time-consuming, but wouldnevertheless be a routine engineering undertaking for those of ordinaryskill in the art having the benefit of this disclosure. The variousembodiments disclosed herein are not intended to limit the scope andspirit of the herein disclosure.

Exemplary embodiments for carrying out the principles of the presentinvention are described herein with reference to the drawings. However,the present invention is not limited to the specifically described andillustrated embodiments. A person skilled in the art will appreciatethat many other embodiments are possible without deviating from thebasic concept of the invention. Therefore, the principles of the presentinvention extend to any work that falls within the scope of the appendedclaims.

As used herein, the terms “a” and “an” herein do not denote a limitationof quantity, but rather denote the presence of at least one of thereferenced items.

In the following description and in the claims, the terms “include” and“comprise” are used in an open-ended fashion, and thus should beinterpreted to mean “include, but not limited to . . . ”. Also, the term“couple” (or “coupled”) is intended to mean either an indirect or directconnection. Accordingly, if one device is coupled to another device,then that connection may be through a direct connection, or through anindirect connection via other components and/or other connections.

The purpose of the intention is to provide a new type of silicone bottlecap that is an improvement of the current technique. The new bottle caphas the features of simple structure, easy operation, and good sealingeffect.

To achieve the above-mentioned features, the silicone bottle capinvented comprises a silicone cap, with its lower end open and expanded,more than two circular sealing ribs inside the cap which are screwedwith the thread on the outside of the mouth of the bottle.

Preferably, as an alternative to the above technical scheme, the lowerend of the cap is equipped with an outward-turning lace.

Preferably, as an alternative scheme, the lace has a wave-like shape.

Preferably, as an alternative scheme, the inside of the cap has parallelsealing ribs.

Preferably, as an alternative scheme, the top of the cap is closed.

Preferably, as an alternative scheme, the top of cap has a closed siteof insertion.

Preferably, as an alternative scheme, the top of the cap hashollowed-out holes.

The benefits of the invention lie in the following aspects: since thewhole bottle cap is made of silicone which is flexible and elastic, thebottle can be sealed by pressing downward the cap onto the mouth of thebottle directly. In addition, the circular sealing ribs inside the capcan be screwed with the threads on the outside of the mouth of thebottle. Therefore, the bottle cap will not easily fall off and thesealing effect can be improved. To remove the bottle cap, the lower endof the cap is flapped and the cap is pulled upwards. The bottle cap isvery easy to use.

As shown in FIGS. 3 to 6, the silicone bottle cap consists of a siliconecap 10, which is cylindrical. The lower end of the cap is open andexpanded, with an outward-turning lace 12, which makes it easy for thecap 10 to fit the mouth of the bottle 100. Lace 12 is wave-like. Toremove the bottle cap, the lace 12 is flapped and the cap is pulledupwards. Then the bottle cap can be separated from the mouth of bottle100.

Inside the bottle cap 10 there are two circular sealing ribs 11 parallelwith each other. The sealing ribs 11 are screwed with the threads 101 onthe outside of the mouth of the bottle 100. Due to the special featuresof silicone, the cap 10 can tightly envelope the mouth of the bottle.Even when the bottle 100 is inverted and shaken violently, the liquid inthe bottle 100 will not leak out.

For beverage bottles, the top of the cap 10 can be made with closed siteof insertion 13, as shown in FIG. 3. The site of insertion 13 iscross-like. When the straw is not inserted in, the site of insertion 13is closed, and the liquid in bottle 100 will not leak out.

Furthermore, the top of the cap 10 can be made with hollowed-out hole14. This design is suitable for bottle used for cultivating flowers. Thebottle cap of such design is also easy to use.

The above content is only preferred embodiments of the presentinvention, for the person of ordinary skill in the art, according to thepresent invention ideas, in a specific embodiment and application scopeswill change place, the contents of this manual should not be interpretedfor limiting the present invention.
